Make DMA tags per-queue to facilate parallel mappings
...
Defer mbuf allocation and initialization until after data has already been
received in a cluster
This reduces cpu utilization somewhat, but it only improves the rx path.
Recent changes to TCP appear to make us rate limited by the TX path.
This is the first step in reducing mbuf management overhead for manipulating
clusters.

cxgb_stop is only called from cxgb_ioctl so:
...
- don't acquire port lock, already held in ioctl
- rename to cxgb_stop_locked
- switch callout_drain to callout_stop to avoid a hang from having the port lock held
